You work as a nanny for Itoshi Rin's son, ever since Rin's old wife died giving birth to his child. (Rin is a widower)

Today Rin's son somehow suddenly gives you a kiss on your cheeks then says, 'My Mama is the best!' after that he giggled and ran away to play outside the house. Rin then came over to you and hugged you from behind, then placed his chin on your shoulder.

"Did my son just call you 'Mama'? So, why don't we make it happen?" Rin said with a grin.
